PLOW.

SPECIFICATION forming part of Letters Patent N 0. 682,587,dated-September 10, 1901. I

Application filed July 16, 1901. Serial No. 68,510. No model.)

To (LZZ whmn/ it may concern:

Be itknown that I, OALVINR. DAVIS, a resident of South Bend,in thecountyof St. Joseph and State of Indiana, have invented certain new anduseful Improvements in Flows; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same. My invention relates to an improvement in plows, and moreparticularly to an improved gage or guide wheel therefor, the object ofthe invention being to provide an improved guidewheel and so mount thesame as to cause the t5 plow to run true and steady and preventvibration and which can be adjusted to various angles to suit theconditions of the soil.

With this object in view the invention consists in certain novelfeatures of construction and combinations and arrangements of parts, aswill be more fully hereinafter described, and pointed out inthe claims.

In the accompanying drawings, Figure 1 is a View in elevation,illustrating my improve- 2 5 ments. Fig. 2 is a rear view, partly insection; and Fig. 3 is a detail View in section.

1 represents a metal beam curved downward at its rear end, forming thestandard A, and then extends forward in the form of an 0 elongated foot,contracted for the attachment of the landside 2, and suitable handles 3are secured to the beam, as shown. The standard A and beam 1 are made ontheir opposite faces with flanges 4 at each edge and a cen- 3 5 traldepression 5, and a disk-spindle box 6 is secured. to the standard andhas mounted therein a spindle to which the rotary disk moldboard 7 issecured.

'A casting 8 is secured on the standard A above the disk-spindle box bymeans of a bolt 9 and is made with grooves and ribs on one side toreceive the flanges 4 on the standard and prevent movement of thecasting when secured in place by the bolt. The other 5 or outer face ofthe casting 8 is made with parallel flanges 10, between which a rod orwheel standard 11 is secured by means of a 1 bolt 12, together wit-hbolt 9, above referred to, and said casting is enlarged between thebolt-holes to permit the relative angle of the standard 11 to be changedby simply loosening one bolt and tightening up the other, the enlargedcentral portion of the casting between the bolt-holes serving as afulcrum on which the standard moves. The standard 11 is bent, as shown,and has secured thereto a scraper 13 (for the guide-wheel 14) by a bolt16, which latter also serves to secure one end of abrace-rod 17 to thestandard 11, the other end of said rod 17 being bent and passed throughone handle3 and screw-threaded on its end for the reception of a nut tosecure the brace in position. The loweror rear end of standardll iswidened and made near each side edge with a hole, alining with holes ina tongue 18, integral with and projecting at right angles to aspindle-box 19, which is made with a slightly-conical bore to receive asimilarly-shaped spindle 20, integral with a plate 21, secured to theguide-wheel 14 by bolts, as shown, and said plate is made with acircular flange 22 to inclose the end of box 19 and prevent the entranceof dirt and grit therein. Said spindle 20 is made with a central holefor the reception of a bolt 23, on which latter a washer 24 is locatedand held in the enlarged and flanged end of the box by a nut 25 tosecure the spindle therein. The tongue 18 is made thickest at its centerbe-- tween the bolt-holes and slopes or inclines to its edges to permitthe relative angle of the tongue and box 19 to be changed by simplyloosening one bolt and tightening the other, as the central or widestportion of the tongue will serve as a fulcrum on which the tongue isturned to change the angle of the guidewheel, as will be readilyunderstood. This guide-wheel 14 runs in the corner of the furrow andlessens the friction of the soil on the landside shoe, also causing theplow to run steady.

The guide-Wheel is made With an oval face, or, in other words, a roundedperiphery, which sinks a short Way into 'the soil, forming a hold forthe wheel and preventing the 5 plow vibrating to either side, thusinsuring a straight and even furrow. Besides, itis found by practicethat the oval-face rim sheds the soil more readily than other forms offace.

It is important that the relative angle of too the wheel-standard to theplow-standard and the guide-wheel to the Wheel-standard can be adjusted,for the plow has a tendency in some soils to Work away from the wall ofthe furrow, and the wheel can, by the means above described, be set atthe proper angle to cause the plow to run true.

Various slight changes might be resorted to in the general form andarrangement of the several parts described without departing from thespirit and scope of my invention, and hence I would have it understoodthat I do not wish to limit myself to the precise details set forth, butconsider myself at liberty to make such slight changes and alterationsas fairly fall within the spirit and scope of my invention.

I do not in this case claim the general features of the plow, the samebeing covered by the claims of my application filed April 29, 1901,Serial No. 58,020.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In a plow, the combination with a standard, of a rotatively-mountedmoldboard on said standard, a wheel-standard projecting rearward fromthe plow-standard, means for adjustablyconnecting the wheel-standard tothe plow-standard, and a wheel adjustably supported by saidwheel-standard behind the cured to the casting by bolts on oppositesides of the raised portion, a wheel-spindle box, a tongue thereonraised or enlarged between its side edges, bolts on opposite sides ofsaid raised portion securing the tongue and wheelstandard together, anda guide-wheel rotatively supported in said box.

3. In a plow, the combination with a standard, a moldboard, a landsideand a point connected with said standard, of a wheel-standard secured tothe plow-standard and projecting rearward therefrom, a guide-wheelrotatively supported at the rear end of the wheelstandard and means forchanging the angle of the wheel with relation to the Wheel-standard andmeans for changing the angle of the wheel standard with relation to theplowstandard.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
